SPECIFICATION forming part of Letters Patent No. 245,048, dated August2, 1881.

Application filed November 6, 1880. (No model.) Patented in France March24, 1880, in Belgium March 80, 1880, and in Italy May 5, 1880. i

1'0 all whom it may concern Be it known that I, EDUARD BARTHELMES,residing at the city of Berlin, in the Kingdom of Prussia, GermanEmpire, have invented Improvements in Magazine Attachments toBreech-Loading Fire-Arms, of which the following is a specification.

.This invention has reference to an improved magazine attachment tobreech-loading fire- IO arms,by means of which a number of cartridgesmay be successively supplied to the barrel of the firearm in connectionwith the operating mechanism of the same, so that the loading of thesame is simplified and a number of shots I 5 may be given in rapidsuccession.

The invention consists of a cartridge-case which is detachably securedto the stock of the fire-arm and provided at the inside with a guidedand spring-pressed plate which forces the cartridges from one side tothe other, so as i to discharge the same successively in connection witha hinged cap, which is set bysuitable lever mechanism either into closedor partially or entirely open position, as required, as

' will appear more fully hereinafter and finally be pointed out in theclaims.

In the accompanyingdrawings, Figure 1' represents a sectional sideelevation of a breechloading firearm with my improved magazine 0attachment, the latter being shown in longitudinal section. Fig. 2 is avertical transverse section, of, the fire-arm and magazine. Fig.3is aside view Fig. 4, a top view, and Fig. 5 a rear view, of the magazineattachment, shown detached from thefire-arm; and Fig. 6 is a verticaltransverse section, on a. smaller scale, of the fire-arm and magazine,showing a modified construction of the attachment.

Similar letters of reference indicate corre- 4o sponding parts.

Referring to the drawings, a represents a casing of sheet-steel, whichis preferably bent in the shape of the letter U, so as .to be capable ofconvenient and. compact attachment to 4 5 the stock below the chamber 6fthe barrel without taking up any extra space or being in the way. Theopening on the left side of the U-shaped casing a is permanently closedby a top plate, I), the overlapping ends of which are secured by screws,as shown in Fig. 5.

In the interior of the casing a is arrangeda stron g spiral spring, d,the upper'end of which is seated against the top plate, I), while theopposite end bears against an angular slide-plate, cl, which correspondsin size to the cross-section of the casing. The spiral spring dis madeof such length and strength that it is capable of forcing the angularslide-plate 01 through theentire length of the U-shaped magazine up tothe right-hand opening of the same.v

7 The slide-plate d is provided with a'fixed stud, d which passesthrougha transverse slot 0 is provided with a side recess, h, into whichthe stud d of the slide-plate d is placed when the slide-plate has beencarried back sufficiently to that side of the casing.

I Before the stud of the slide-plate d can be set into the recess h ofthe slot 6 it is'neces-. sary to push a pivoted guard, s, sidewise,after which the stud of the slide-plate can enter into the recess h, asshown in Fig. 4. The spiral 8o spring d is thereby reliably retained bythe slide-plate in compressed position at one side of the magazine, inwhich position the interior space of the casing a may be'readily chargedwith cartridges. 8 5

The front and rear end walls of the magazine a are provided at theright-hand side with bracket-shaped extensions or ears on, to whicha'semicircular cap, 0', is hinged by a pintle, k; This cap is adapted tocover the right hand 0 opening of thecasing a, and is made, like thebody of the casing, witha taper, which corresponds to the usual taper ofthe cartridges used in breech-loading fire-arms.

- The semicircular cap '5 can be set into three 9 5 diiferent positions,and securely, retained in of the casing, by which slot the .ward motionof the lever-arm Zis controlled.

either of the same by means of two pivoted retaining-lever arms, oand l,which are clearly shown in Figs. 3, 4, and 5. The pivoted arm I, Fig. 5,turns around the sorew-stud m, and projects by apin into a slot, 11, ofthe rear wall extent of up- In similar manner the lever-arm turns on ascrew-stud, p, and passes by a pin, q, through a slot, r, of therearbracket-plate, a of the easing, the slot '1' defining the extent ofside motion .of the lever-arm 0.

For placing the cap 2' into the first or closed position the lever-armlis left in its downward position, and the lever-arm o carried towardthe left, so as to abut against the projecting hook-shaped end of thelever-arm Z. In this position the arm 0 retains'the cap '5 in closedposition.

I the right as far as the slot 1' admits, in which position the shank 'vof the cap abuts against the pin q and produces the partial opening ofthe cap '5, as shown clearly in Fig. 2. When the cap '5 is closed thecartridges are securely retained within the casing, but ready to becharged into the barrel of the fire-arm. In this position'the stud ofthe slide-plate is released, so that the latter is forced by the springupon the cartridges, and moves them forward against the cap 7:, whichreceives thereby atendency to be thrown open, which, however, isprevented by the pin got the lever-arm o. By throwing the lever-arm osidewise the cap 2' is instantlythrown into the third or partially openposition by the pressure of the spiral spring, until its shank 0 formscontact with the pin q. The-cartridges follow the motion of the cap, theupper one being partly embraced by the semicircular cap a, the lowershorter part of which, below'the shank r, enters between the first andsecond cartridge, and prevents, thereby, the latter, as well as all theremaining cartridges, being thrown out of the magazine by the pressureof the spiral spring. In thisposition of the cap t the uppermostcartridge is readily dropped sidewise into the open barrel of thefirearm. By pressing the cap t downward the lowershorter part of thesame forces the cartridges slightly downward, and permits the uppermostcartridge again to pass beyond it and place itself in position in theupper longer partof the cape, so that by resetting the lever the nextcartridge can be thrown out and the remaining ones held inside'of themagazine. By thus opening and closing thecap c" one cartridge after theother can be successively and reliably supplied from the magazine to thebarrel of the fire-arm.

The magazine a is attached to the stock of the fire-arm by means of adovetailed piece, t, which is rigidly screwed to the under side of thestock.

From the inner wall of the magazine are bent up two lugs, sides of thedovetailed piece t, which lugs are slid over the piece so as to retainthe magazine against lateral displacement. A band-sprin g, t, is,furthermore, centrally riveted to the inner wall of. the magazineandextended longitudinallyalong the same.

The spring t is provided with hook-shaped projections t t, which enterinto notches of the fixed dovetailed piece t, so as to prevent naldirection when once placed in proper position on the stock. If'a smallernumber of -cartridges is desired to be stored in the magansed, which islocked to the side of the fire-arm, though the U-shape form is in everyrespect preferable, as it is more compact and does not interfere withthe handling of the fire-arm- A For charging the magazine withcartridges the cap t is thrown into entirely open position and theslide-plate (1 locked into the recess of the slot e. The cartridges arethen inserted and the cap 2' closed whenthe magazine is encan be carriedin any desired manner detached from the stock until required for use. Itis then looked to the stock of the fire-arm, after which the spring atis released and the guard s carried over the recess h, so as to preventthe accidentalresettin g of the stud of' the side plate in the recess h.

The breech-loading fire-arm may be supplied for any length of time withsingle rounds from order for rapid firing is given, when the magazine isplaced in position on the stock. The

release the cap 6, which is, however, held in closed position by thelever-handle of the movable portionof the chamber of the fire-arm. Byturning the handle of the chamber from right to left the shell of thecartridge is first thrown out by means of the extracting devices, whichare indicated in Fig. 1, respectively, by the letters A and B, theextractor Aen gaging the shell and carrying the same back within thechamber until the rim of the cartridge is. arrested by the fixedprojection B, by which the cartridge is upset and thrown out of thechamber. As the pressure of the handle on chamber the cartridge isplaced in properposition into the chamber of the fire-arm and the thecap 0' is thrown of the. cartridges,

the same is turned over from the left to the right.

lever-arm 0 is then carried sidewise, so as to I t, at the sameinclination as'the any displacement of the magazinein longitudizine, thestraightform shown in Fig. 6 may be tirely filled. In this conditionthe'magazine ice I 0 the cartridge-box in the usual manner, until thethe/cap t is released in opening the chamber,

cap t closed againby the lever-handle, when i 3 The magazine shown inthe drawings is capable of taking up eleven cartridges, which,

in connection with the cartridge in the barrel, furnish twelve rounds,which can be rapidly fired one after the other by the simple opening andclosing of the cartridge-chamber of the barrel by the handle, withoutremoving the hand therefrom during this operation. manner the fire-armis almost instantlyreloaded, and admits the firing of a dozen shots inrapid succession. The magazine is removed from the stock by simplypressing with the hand upon the bottom of the magazine, so that thelocking-spring may be released, and the r magazine detached from thestock.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent- 1.
